Brief Summary:
This randomized phase III trial compares memantine hydrochloride and whole-brain radiotherapy with or without hippocampal avoidance in reducing neurocognitive decline in patients with cancer that has spread from the primary site (place where it started) to the brain. Whole brain radiotherapy (WBRT) is the most common treatment for brain metastasis. Unfortunately, the majority of patients with brain metastases experience cognitive (such as learning and memory) deterioration after WBRT. Memantine hydrochloride may enhance cognitive function by binding to and inhibiting channels of receptors located in the central nervous system. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Using radiation techniques, such as intensity modulated radiotherapy to avoid the hippocampal region during WBRT, may reduce the radiation dose to the hippocampus and help limit the radiation-induced cognitive decline. It is not yet known whether giving memantine hydrochloride and WBRT with or without hippocampal avoidance works better in reducing neurocognitive decline in patients with brain metastases.

Detailed Description:

PRIMARY OBJECTIVES:

I. Determine whether the addition of whole-brain radiotherapy with hippocampal avoidance (HA-WBRT) increases time to neurocognitive failure at months 2, 4, 6, and 12 as measured by neurocognitive decline on a battery of tests: the Hopkins Verbal Learning Test-Revised (HVLT-R) for Total Recall, Delayed Recall, and Delayed Recognition, Controlled Oral Word Association (COWA), and the Trail Making Test (TMT) Parts A and B.

SECONDARY OBJECTIVES:

I. Determine whether the addition of HA-WBRT preserves neurocognitive function at months 2, 4, 6, and 12 as separately measured by each test, the HVLT-R for Total Recall, Delayed Recall, and Delayed Recognition; COWA; and TMT Parts A and B.

II. Evaluate the potential benefit of HA-WBRT in symptom burden, as measured by the M. D. Anderson Symptom Inventory-Brain Tumor Module (MDASI-BT).

III. Assessment of quality adjusted survival and cost analysis using the five-level version of the EuroQol five-dimensional (EQ-5D-5L).

IV. Compare cumulative incidence of progression and overall survival after WBRT versus HA-WBRT.

V. Compare adverse events between the treatment arms according to the Common Terminology Criteria for Adverse Events (CTCAE) version (v)4.0 criteria.

TERTIARY OBJECTIVES:

I. Collect serum, plasma, and imaging studies for future translational research analyses.

II. Evaluate magnetic resonance (MR) imaging biomarkers of white matter injury and hippocampal volumetry at baseline and 6 months as potential predictors of neurocognitive decline and differential benefit from HA-WBRT as compared to WBRT.

III. Association of symptom burden and anxiety/depression with neurocognitive function.

IV. Evaluate the potential correlation between the prognostic scoring systems Radiation Therapy Oncology Group (RTOG) recursive partitioning analysis (RPA) and the diagnosis-specific graded prognostic assessment (DS-GPA) and neurocognitive function at baseline and overtime.

After completion of study treatment, patients are followed up at 12 months.

Primary Outcome Measures :
  1. Time to Neurocognitive Failure [ Time Frame: From randomization to last follow-up. Maximum follow-up was 15.6 months. ]
    Neurocognitive failure is defined as the first failure, defined as a neurocognitive decline using the reliable change index (RCI) on at least one of the following assessments or parts of : Hopkins Verbal Learning Test - Revised (HVLT-R), Trail Making Test (TMT), or Controlled Oral Word Association (COWA). The HVLT-R has 3 parts that were analyzed separately for decline: Total Recall, Delayed Recall, and Delayed Recognition. The TMT has 2 parts that were analyzed separately: Part A and Part B. Neurocognitive failure rate is estimated using the cumulative incidence method. Analysis was planned to occur after 233 events were reported. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Six-month rates are provided.Analysis was planned to occur after 233 events were reported.


Secondary Outcome Measures :
  1. Change From Baseline in the Hopkins Verbal Learning Test -Revised (HVLT-R) Total Recall Score (Neurocognitive Decline) [ Time Frame: Baseline, 2, 4, 6, and 12 months ]
    The HVLT-R assesses verbal learning and memory. The test involves memorizing a list of 12 nouns for 3 consecutive trials (Total Recall), recalling the 12 targets after a 20-minute delay (Delayed Recall), and then identifying the 12 targets from a list of semantically related or unrelated items (delayed recognition). Raw scores are derived for total recall (sum of the number of targets correctly recalled), delayed recall (sum of the number of targets correctly recalled), and a delayed recognition discrimination index (sum of targets incorrectly identified subtracted from the sum of the number of targets correctly identified). The range of scores for total recall is 0 to 36, for delayed recall is 0 to 12, and -12 to 12 for recognition. A higher score indicates better functioning. Scores are standardized, adjusting for age, education, and gender as necessary, such that mean 0 and standard deviation is 1. Change is calculated as baseline score subtracted from post-baseline score.

  2. Change From Baseline in the Hopkins Verbal Learning Test -Revised (HVLT-R) Delayed Recall Score (Neurocognitive Decline) [ Time Frame: Baseline, 2, 4, 6, and 12 months ]
    The HVLT-R assesses verbal learning and memory. The test involves memorizing a list of 12 nouns for 3 consecutive trials (Total Recall), recalling the 12 targets after a 20-minute delay (Delayed Recall), and then identifying the 12 targets from a list of semantically related or unrelated items (delayed recognition). Raw scores are derived for total recall (sum of the number of targets correctly recalled), delayed recall (sum of the number of targets correctly recalled), and a delayed recognition discrimination index (sum of targets incorrectly identified subtracted from the sum of the number of targets correctly identified). The range of scores for total recall is 0 to 36, for delayed recall is 0 to 12, and -12 to 12 for recognition. A higher score indicates better functioning. Scores are standardized, adjusting for age, education, and gender as necessary, such that mean 0 and standard deviation is 1. Change is calculated as baseline score subtracted from post-baseline score.

    The HVLT-R assesses verbal learning and memory. The test involves memorizing a list of 12 nouns for 3 consecutive trials (Total Recall), recalling the 12 targets after a 20-minute delay (Delayed Recall), and then identifying the 12 targets from a list of semantically related or unrelated items (delayed recognition). Raw scores are derived for total recall (sum of the number of targets correctly recalled), delayed recall (sum of the number of targets correctly recalled), and a delayed recognition discrimination index (sum of targets incorrectly identified subtracted from the sum of the number of targets correctly identified). The range of scores for total recall is 0 to 36, for delayed recall is 0 to 12, and -12 to 12 for recognition. A higher score indicates better functioning. Scores are standardized by expressing the deviation from the mean score of the group in units of standard deviation. Change is calculated as baseline score subtracted from post-baseline score.

  4. Change From Baseline in the Trail Making Test (TMT) Part A (Neurocognitive Decline) [ Time Frame: Baseline, 2, 4, 6, and 12 months ]

Subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. There are two parts to the test: in the first (Part A), the targets are all numbers (1, 2, 3, etc.) and the test taker needs to connect them in sequential order; in the second part (Part B), the subject alternates between numbers and letters (1, A, 2, B, etc.). The score is the amount of time, in seconds, that it takes the patient to complete each maze. The range for Part A is 0 to 180 (3 minutes) and for Part B is 0 to 300 (5 minutes). Lower scores indicate better functioning. Scores are standardized, adjusting for age, education, gender as needed, so that mean is 0 and standard deviation is 1. Change is calculated as baseline score subtracted from post-baseline score.

  5. Change From Baseline in the Trail Making Test (TMT) Part B (Neurocognitive Decline) [ Time Frame: Baseline, 2, 4, 6, and 12 months ]

The score is the amount of time, in seconds, that it takes the patient to complete each maze. The range for Part A is 0 to 180 (3 minutes) and for Part B is 0 to 300 (5 minutes). A lower score indicates better functioning. Scores are standardized by expressing the deviation from the mean score of the group in units of standard deviation. Change is calculated as baseline score subtracted from post-baseline score.

  6. Change From Baseline in the Controlled Oral Word Association (COWA) Test (Neurocognitive Decline) [ Time Frame: Baseline, 2, 4, 6, and 12 months ]
    The COWA is a verbal fluency test that measures spontaneous production of words belonging to the same category or beginning with some designated letter. Patients are given 1 minute to name as many words as possible beginning with the designated letter. The procedure is then repeated for the remaining two letters. Two alternate forms of the COWA are employed to minimize practice effects. The score is the sum of the correct responses with a range of 0 to infinity. A higher score indicates better functioning. Scores are standardized, adjusting for age, education, and gender as necessary, such that mean is 0 and standard deviation is 1. Change is calculated as baseline score subtracted from post-baseline score.

  7. Change From Baseline in the Clinical Trial Battery Composite (CTB COMP) Score [Neurocognitive Decline] [ Time Frame: Baseline, 2, 4, 6, and 12 months ]
    Clinical Trial Battery Composite score is the arithmetic mean of the HVLT-R (Free Recall, Delayed Recall, Delayed Recognition), TMTA, TMTB, and COWA scores, all of which are standardized, adjusting for age, education, and gender as necessary, such that mean is 0 and standard deviation is 1. A participant must have at least 5 of the 6 scores. A higher composite score indicates better neurocognitive function.Change is calculated as baseline score subtracted from post-baseline score.

    . Adverse events were graded using the Common Terminology Criteria for Adverse Events (CTCAE) v3.0. Grade refers to the severity of the AE. The CTCAE v3.0 assigns Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild, Grade 2 Moderate, Grade 3 Severe, Grade 4 Life-threatening or disabling, Grade 5 Death related to AE.


Other Outcome Measures:
  1. Anxiety/Depression Measured Using the EQ-5D-5L [ Time Frame: Up to 12 months ]
    An exploratory analysis, beginning with correlation coefficients, will be used to assess the association of symptom burden and anxiety/depression with neurocognitive function at each time point. The symptom burden items of interest are the "distressed (upset)", "sad", and "mood" items. From the EQ-5D-5L, the depression/anxiety item will be of interest.

    Neurocognitive function, as measured by the HVLT-R, COWA, and TMT, will be correlated with both the RTOG RPA and the DS-GPA classification systems. Baseline neurocognitive function for each test will be compared between both RPA classes using either a t-test or Wilcoxon-Mann-Whitney test, depending on the normality of the data.

  3. Effect of White Matter Injury and Hippocampal Volume on Neurocognitive Function [ Time Frame: Up to 12 months ]
    Evaluated through MRI scans using physician-contoured and auto-contoured scores. Concordance rates will be assessed using Kappa statistics. The auto-contoured scores will be used for the remaining analyses due to the number of physicians reviewing the scans. White matter injury is measured by FLAIR volume change and is a continuous variable. Hippocampal volume is measured as a continuous variable also and both will be covariates considered in the Cox proportional hazards model to assess the impact on time to neurocognitive failure and the longitudinal modeling of neurocognitive function.

  4. MDASI-BT Mood Variables [ Time Frame: Up to 12 months ]
    The relationship between EQ-5D-5L and MDASI-BT mood variables and neurocognitive function will be assessed.
